WIRE-CUTTING BAYONET.

Be it known that I, CASEY SZAFRANSKI,

a citizen of the United States of America, residing at South Chicago,.in the county of Cook and State of Illinois, have invented certain newand useful Improvements in ire-Cutting Bayonets, of which the followingisa specification.

The primary object of the invention is the provision of a ready meanscarried by a for cutting wire entanglements and similar obstructionsoffered by the enemy to the line of march, the device being simple inconstruction and adding no material Weight to the fire arm providedtherewith.

A further objectof the invention is the provision of an attachment forthe bayonet I of a rifle for readily cutting Wires when operatedby thesoldier or other person holdingthe gun in any usual manner,'theoperation of theudevice being in the nature of shearing.

i In the drawing forming a part of this application E 1 throughout andin which like designating refer to corresponding parts the severalviews,

characters a Figure 1 is a side elevation of the device mounted upon thebarrel of a rifle.

,Fig. 2 is a view similar toFig. 1 with the wire cutting member closed.Fig. 3 is a view taken upon line III-III ofFig. 2.

. Fig. 4 is a transverse sectional view taken V--V of Fig. 2, and

uponline is anenlarged fragmentary view of the operating connections forthe shearing blade. It will be understood that my device may be.attached to the usual form of bayonets I such as and which bayonetsprovide op- ,posite cutting edges nally thereof, while 11 extendinglongitudithe bayonet 10 is adaptedfor rigid attachment to a gun barrelsuch 1 I: asm12 by means ofabracket 13.

i While my invention is primarily in the j form of an attachment for.the bayonet 10, it will be noted that the bayonet is a necesin weightand adds very Patented May 21, 1918.

Application filed February 11,1918. Serial No. 216,554.

sary element as one of the edges 11 of the bayonet assists in the,cutting operation. A shearing blade 14 is pivoted as at 15 betweenopposite plates 16 secured to a flat shank portion 17 of the bayonet 10,the arrangement being such that the cutting edge 18 of the blade 14 ispositioned op osite the outer edge 11 of the bayonet 10 or cooperatingtherewith during the cutting operation when the blade 14 is pivotallymoved upon its hinge-15.

An operating rod 19 is provided for the blade 14 being operativelyattached by means of a link 20 to a curved rocker arm 21 pivoted as at22 to the bayonet shank 17 and having a loose connection 23, of the pinand slot variety, the said blade 14.

. The rod 19 extends to any convenient.

point of operation adjacent the rifle, such for instance as a pointadjacent the butt or stock thereof, not shown, and the said rod 19 maybe extended through a tubular guide 25 carried beneath thebarrel 12 iffound desirable. While carrying the gun provided to sever a wire such as26, the wire i positioned between the cutting edges 11 and 18 while therod 19 1s pulled rearwardly 1n the direction indicated by the arrow inFig. 2 of the drawing and this operation forces the blade heel 24 in adirection away from the bayonet 10 thereby forcing the edge 18 of theblade 14 toward the adjacent edge 11 of the bayonetlO and cuttingthrough the wire 26 positioned between the said edges.

The attachment herein described is light little weight or bulk ofmaterial to the ordinary form of un barrel and bayonet while the deviceis always ready for instant usein cutting wire entanglements and similarbarriers.

What I claim as new is A device of the class described comprising incombination with a gun barrel having a bayonet mounted thereon and ar- Qf 4, i I "1,266,640:
